It's not stated specifically that a ship can only have one computer. If you want to give bonuses to more characters that is allowed by the restrictions on computers (no more than 4 bonuses, no more than 3 bonuses greater than 3 no more than 2 bonuses greater than 5).
Optionally there could be a limit of no more bonuses of +X or greater than you could get with one computer. So if you had a Mk 10 duonode you couldn't add any Mk. 6s or greater because that would mean more than 2 nodes of 6 or better, but you could add a Mk. 4 or
5 mononode or you could add two Mk. 3s or less.

Technically the ships computer is free, only the interface has a cost.
The way I see a ships computer is a network of individual systems. The max bonus is a representation of the physical interface and how well the system is networked. The number of bonuses is primarily how well it is networked. For example a Mk 2 duonode has upgraded consoles at all stations and can handle two networked paths at a time. The gunner takes one bonus and the computer links his console to the sensors giving better targeting data and motion prediction. The pilot takes the other bonus linking the controls with the nav computer to more precisely adjust the drive output.
As a house rule you could try allowing the computer to act as any lower model with a lower BP cost. A MK 4 Duo (32) could act as a MK 3 Tri (27) or Mk 2 Tetra (16) but not a MK 3 Tetra (36).
